PC의 빠른 보급으로 많은 사용자가 PC로 다양한 콘텐츠를 즐기고 있다. 특히 최근 들어 청소년들의 PC이용 률이 급격히 증가했다. 청소년들은 이러한 PC를 이용하여 보다 쉽게 정보를 얻을 수 있고, 특히 온라인 게임을 통하여 스트레스를 해소하고, 가상현실에서의 또 다른 재미를 느낄 수 있다. 이렇게 일찍부터 빠르게 발전하고 있는 IT문화를 접하는 것은 좋은 일인 것은 분명하다. 하지만 그로 인해 청소년들은 자연스럽게 실내 활동이 많아지게 되면서 야외활동이 줄어들게 됨에 따라 세상을 보는 시야 또한 많이 좁아지게 되었다. 따라서 청소년 들의 야외활동을 유도하기 위해 최근 많이 사용하는 스마트 폰 어플리케이션을 이용하여 현장체험 쿠폰 시스템을 구축하게 되었다. 그리고 HTML5를 기반으로 하는 하이브리드 앱을 개발함으로써 디바이스의 구분없이 사용할 수 있도록 하였다. 따라서 이 어플리케이션을 통해서 청소년들의 현장체험에 대한 관심과 동기를 유발시킴으로써 많은 볼거리를 체험하고, 다양한 시각에서 세상을 바라볼 수 있다. Because of rapid spread of the PC, many users have been enjoying a variety of content as PC. Especially in recent years, young people has increased dramatically PC usage. Young people get more easily information using a PC. Especially they relieve their stress through online games and feel another fun of virtual reality. It is obviously a good effect that they contact IT culture with rapidly developed. But young people`s perspective with world is narrow because of doing more indoor activities than outdoor. Therefore we built Spot experience voucher system using smart phone application. We hope that many young people act outdoor activities. And Our product offer hybrid device by developing HTML5-based app. Thus this app will give interest of spot-experience to young-people. So If young people use this app, they can have many experience and see diverse aspects.

문용화,김지현,강웅철,박병은,고영국,최동훈,유경종 대한내과학회 2004 대한내과학회지 Vol.66 No.3

관동맥우회술을 포함한 심장수술 후에 생기는 급성 장간막경색은 매우 드물지만 치명적인 합병증으로 발생률은 비교적 낮으나 사망률은 매우 높게 보고 되고 있다. 본 증례에서는 55세 여자 환자가 관동맥우회술을 시행받고 수술 후 1일째에 발생한 복부통증에 대해서 장간막경색증을 의심하지 못하고 수술과 연관된 비특이적 증상으로 판단하였으나 그 후 환자의 증상이 악화되면서 상장간막동맥 혈전 색전증에 의한 광범위한 급성 장괴사로 판명되었다. 관독맥우회술 후 상장간막 동맥에 생긴 혈전색전증에 의해 발생한 급성 장간막경색의 증례는 국내에 보고된 바 없고 본 증례를 통해 교육적인 경험을 하였기에 저자들은 문헌고찰과 함께 보고하는 바이다. 심폐우회술을 요하는 심장수술을 받은 환자 중 특히 급성 장간막허혈의 위험인자를 가지고 있는 환자에 대해서는 급성 장간막허혈이 생길 수 있다는 세심한 관찰이 진단이 늦어지지 않게 하는 방법이며 장간막허혈이 의심되면 즉시 적극적인 진단 및 치료적인 접근을 시도해야 하겠다. Acute mesenteric ischemia leading to massive bowel infarction following cardiac surgery particularly coronary artery bypass graft (CABG), is reported to be a very rare but serious life-threatening complication. In this case, a 55-year-old female underwent CABG and complained of abdominal pain on the first postoperative day, which was thought to be nonspecifically related to the operation wound, In the further hospital course, the patient was found to have extensive acute mesenteric infarction due to thromboembolism of superior mesenteric artery. This is a valuable educational case, since only high index of suspicion does not delay making a diagnosis especially in the patients with risk factors of acute mesenteric ischemia after cardiac surgery requiring cardiopulmonary bypass. On suspicion of acute mesenteric ischemia, an aggressive diagnostic and therapeutic approach should be performed immediately.(Korean J Med 66:317-320, 2004)

저용량 Droperodol 의 지속적 정맥내 주사가 방사선 치료로 유발된 구토에 대한 효과 : As a Substitution for Granisetron for the Treatment of Gastrointestinal Symptoms from Palliative Radiation Therapy

문성록,박수경,정영표,김태요,최유선 圓光大學校 醫科學硏究所 1998 圓光醫科學 Vol.14 No.2

Background: Radiation therapy in palliative cancer management leads mainly to nausea, vomiting, dyspepsia and anorexia. Several agents have been used to treat above symptoms and sings. We assessed the usefulness of continuous intravenous infusion of low-dose droperidol, compared to granisetron for the control of gastrointestinal symptoms due to radiation therapy. Method: We devided 30 patients who developed gastrointestinal symptoms after undergoing palliative radiation therapy due to metastatic bone pain in two groups. In group G(n=15), the patients were injected granisetron(3㎎) and then injected it, 3㎎ per day. In group D(n=15), the patients were injected low-dose droperidol(0.25㎎) and then infused continuously at low-dose(1㎎/day) by the disposable continuous infusion pump. Result: There were no significant differences in the patient's satisfaction, improvement of appetite and incidences of side effects between two groups. Conclusion: The continuous intravenous infusion of low-dose droperidol can substitute for serotonin-receptor antagonist for the treatment of gastrointestinal symptoms during radiation therapy for cancer patients.

유영문,남성운,이종광,오병성,이기선 충남대학교 기초과학연구소 1997 忠南科學硏究誌 Vol.24 No.2

Structural and optical properties of polycrystalline ZnTe films, deposited at various substrate temperatures by vacuum evaporation, have been investigated by X-ray diffraction and transmission. The grain size was increased with increasing substrate temperature. The allowed direct band gap and the indirect band gap were found to be 2.25 ∼ 2.27 eV and 2.05 ∼ 2.20 eV, respectively. The absorption coefficient, the extinction coefficient and the refractive index were obtained as a function of the incident photon energy. Near the band edge, the absorption coefficient and the extinction coefficient were about 10^3 ∼ 10^4 ㎝^1 and 10^-1 ∼ 10^-3, respectively. And the refractive index was 2.8 ∼ 3.2.

문형배,소병준,김학철,윤기중,한원철,조향정,유대열,정영진 圓光大學校 醫科學硏究所 2002 圓光醫科學 Vol.17 No.2

<연구목적> HBx형질전환 생쥐에서 발생한 간세포암종의 발암과정에 종양유전자(H-rgs, c-myc)의 발현 정도를 조사하고자 하였다. <연구방법> 정상생쥐 12마리(4-18개월) 및 HBx 형질전환 생쥐 44마리(4-18개월)를 대상으로 포르말린에 고정하고 파라핀에 포매한 간 조직을 이용하여 면역조직화학적염색을 실시하였다. 실험군은 정상 부위, 이형성 부위 및 종양 부위로 구분하였으며, 종양 부위는 소결절성병변 부위와 간세 포암종 부위로 구분하였고, 이형성병변 부위는 이형성병변만 발견되는 부위, 소결절성병변과 동반된 이형성병변 부위 및 간세포암종과 동반된 이형성병변 부위로 구분하였다. <연구결과> H-rgs의 발현은 정상 간조직에 비하여 이형성병변 부위(P<0.05) 및 종양 부위(P<0.01)에서 증가하였으며, 소결절성병변 부위과 간세포암종 부위 사이에서는 간세포암종 부위에서 증가된 경향이었으나 통계학적으로 유의한 차이가 없었으며, 각 이형성병변 부위 사이에서도 유의한 차이는 없었다. c-myc의 발현은 정상 간조직 및 이형성병변 부위에 비해 종양 부위에서 증가하였으며(P<0.001), 소결절성병변 부위와 간세포암종 부위에서는 비슷하였고, 각 이형성병변부위 사이에서도 비슷하였다. <결론> HBx형질전환 생쥐에서 발생하는 간세포암종의 발생에 H-rgs는 이형성 변화를 일으키는 시기에 관여하며, c-myc은 이형성병변에서 암으로 이행하는 시기에 관여할 것으로 생각한다. Background: This experiment was designed for the expression of H-ras and c-myc in hepatocarcinogenesis of the HBx transgenic mice. Methods: Immunohistochemical stains in the paraffin embedded tissue of the liver were used for the detection of H-ras and c-myc in the 12 normal mice and 44 HBx transgenic mice of the 4-18 month old. Results: Expression of the H-ras was significantly increased in the dysplastic area (P<0.05) and tumor area (P<0.01) than in the normal liver. But there were no differences of H-ras expression between areas of microscopically identified hepatocellular carcinoma (MI-HCC) and grossly identified hepatocellular carcinoma (GI-HCC) and dysplastic areas among the only dysplastic areas, dysplastic areas with MI-HCC and GI-HCC. Expression of the c-myc was significantly increased in the tumor area (P<0.001) than in the normal liver and dysplastic area. But there were no differences of c-myc expression between areas of MI-HCC and GI-HCC, and dysplastic areas among only dysplastic areas, dysplastic areas with MI-HCC and GI-HCC. Conclusions: Our study suggests that H-ras is related to the dysplastic change and c-myc is related to the neoplastic change in the hepatocarcinogenesis of the HBx transgenic mice.

The clastogenic effects of the diesel emission particle extrace(DEPE), mercuric chloride and lead acetate were examined by the mouse bone marrow micronucleus test. DEPE had a potent clastogenic effect by intraperitoneal injection with dose-response between 100 and 300mg/kg b.w.. Mercuric chloride and lead acetate also gave a clastogenic effects but mercuric chloride only had a dose-response between 1 and 3mg/kg b.w.. When DEPE was administrated with mercuric shloride or lead acetate, the frequency of micronucleated cells was slight but not significant incresase in comparision to a single treatment with DEPE alone.

This study is carried out to investigate the water quality change trends in Pusan Metropolitan streams. The temperature of the streams are moderate except in winter period and this can be explained by the Korean meterological characteristics. The pH does not vary by the time but some points are a little low. BOD_(5) and COD_(Mn), the index of water contaminants, be shown as characteristic domestic waste water patterns. The nutrient matters, such as total nitrogen and total phosphate, are appeared to be low. The chronic water quality, as BOD_(5) and COD_(Mn), shows that the loading rates in 1998 are smaller than the past(1983, 1992). Some points show a little high loading in autumn, but this needs more investigation to make clear the cause(s).

Azelastine, a phthalazinone derivative, is an antiallergic agent which demonstrates histamine H_1-receptor antagonist activity and also inhibits histamine release from mast cells following antigen and non-antigen stimuli. Thus, azelastine may be useful in the management of both asthma and allergic disorders. The purpose of the present study was to evaluate the bioequivalence of two azelastine hydrochloride tablets, Azeptin^TM (Bu Kwang Pharmaceutical Co., Ltd.) and Azela^TM (Kyung Dong Pharmaceutical Co., Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). Eighteen normal male volunteers, 22.44±2.01 years in age and 61.99±6.18㎏ in body weight, were divided into two groups and a randomized 2×2 cross-over study was employed. After two tablets containing 1㎎ of azelastine hydrochloride per tablet were orally administered, blood was taken at predetermined time intervals and the concentrations of azelastine in serum were determined using HPLC with fluorescence detector. Pharmacokinetic parameters such as AUC_t, C_max and T_max were calculated and ANOVA test was utilized for the statistical analysis of the parameters. The results showed that the differences in AUC_t, C_max and T_max between two tablets were -6.45%, -2.60% and -7.14%, respectively, when calculated against the Azeptin^TM tablet. The powers (1-β) for AUC_t and C_max were 96.65% and 88.47%, respectively. Minimum detectable differences (Δ) at α=0.05 and 1-β=0.8 were less than 20% (e.g., 14.40% and 17.65% for AUC_t and C_max, respectively). The 90% confidence intervals were within ±20% (e.g., -14.87∼1.97 and -12.92∼7.72 for AUC_t and C_max respectively). Two parameters met the criteria of KFDA for bioequivalence, indicating that Azela^TM tablet is bioequivalent to Azeptin^TM tablet.

폐렴 구균(Streptococcus pneumoniae)에 의한 척수 경막외 농양 1예

이지영,위유미,손경목,기현균,문치숙,오원섭,백경란,송재훈 대한감염학회 2004 감염과 화학요법 Vol.36 No.6

폐렴구균은 보통 폐렴이나 뇌막염을 일으키는 균으로 척수 경막외 농양을 일으키는 경우는 매우 드물다. 본 저자들은 폐렴 구균에 의한 척수 경막 외 농양을 경험하여 보고하는 바이다. 과거 건강했던 36세 남자 환자로 사다리에서 낙상한 후 요통 및 고열, 신경학적 이상으로 내원하여 자기 공명 촬영 결과 척수 경막 외 농양으로 진단받고 항균제 투여와 함께 응급 수술을 시행하였다. 농 배양 결과 페니실린 감수성인 폐렴 구균이 분리 되었고, 수술 요법과 항생제 투여 후 농양은 치유되었으나 신경학적 이상은 호전 없는 상태로 타원으로 전원되었다. Pneumonia and meningitis are the most frequent manifestations of pneumococcal infections. Pneumococcal spinal epidural abscesses have been rarely reported. Spinal epidural abscess by Streptococcus pneumoniae has been diagnosed among the patients with diabetes mellitus, alcoholism, corticosteroid therapy, intravenous drug use, chronic renal failure, AIDS, and history of spinal surgery. Recently, we experienced a case of pneumococcal spinal epidural abscess after spinal trauma. A 36-year-old male patient was admitted with back pain, fever, and paraplegia which occurred 5 days after the trauma. Spine MRI revealed spinal epidural abscess at the level from T2 to T9. He was treated with antimicrobial agents and surgical exploration for spinal epidural abscess. Pus culture grew S. pneumoniae which was susceptible to penicillin. Despite early surgical treatment, neurologic sequelae remained. Considering the high mortality and morbidity of pneumococcal spinal epidural abscess, early diagnosis and aggressive treatment including surgical intervention and antibiotics therapy should be implemented immediately.
